I think my comments on the thread at MMSA explain the issue nicely.
My response to your post:
All the above is fair enough, but it is surely the icons above all which determine whether a reader goes into a story. I just went into Ricky Scarma's personal thread and there you said of one of his stories: "The mom spanking is basically a supporting role in this story. It is one of those things that is mentioned just enough to make it relevant but it is definitely NOT the main event. I had to tag it but please do not let it turn you away." The icons attached to the story do not say that, but a blurb to the same effect would.
There was a time when the number of icons was restricted, I think to something like 4 or 5. I am not suggesting we go back to that, but when we had it a reviewer had to give consideration to which features were the most significant; readers were less likely to be disappointed or miss out on a story they would have enjoyed.
The F icons in particular have the potential to be misleading. Broadly, stories featuring female spankers will divide into those which involve routine spankings by women in a domestic or school setting and those which involve a significant femdom element. There is a qualitative difference between the two which the icons do not indicate. Given the number of stories in the archive with F icons it is too late to do anything about that, but a blurb attached to new stories would help the reader.
I cannot help feeling that blurbs would be a feature welcomed by some authors and readers. Those who do not want it can simply ignore it.
